Application filed September 3, 1910. Serial No. 580,442.

I To all whom it may concern."

Be it known that l, Lrnonn OSLAND, a citizen of the United States, and aresident of. Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Bilged Metallic Package,

and I do hereby declare the following to be in the art to which itappert-ains to .make and use the same, reference being had to theaccompanying ures of reference marked thereon, which form a. part ofthis specification.

My invention relates to metallic packages,

and particularly to the construction of bilged sheet-metal barrels. Inthe manufacture of packages of this class, it has been customary tolongitudinally rib the same, and in order to take up enough metal togive the barrels the proper bilge,.the ribs have been gradually narrowedfrom their ends inwardly, thus producing the. weakest point at themiddle of the package.

The object of my invention isto overcome.

the objection incident to the old construe $5011 of bilged barrels ofthe class described,

y so forming and arranging the reinforcing ribs as to make the packagebody of-substantially equal strength throughout its length and at. thesame time impart a bilge formation thereto.

The invention is fully described in the following specification, andwhile, in its broader aspect, it is susceptible of embodiment innumerous forms, a preferred embodiment thereof is illustrated in theac.- companying drawings, in which,-

Figure l is a central longitudinal section of abarrel body embodying myinvention. Fi 2 is a central cross-section thereof on the line 2 2 inFig. 1 Fig. 3 is an end view ofthe barrel body. Fig. 4 is across-section on the line i l in Fig. 1. Fig. 5 is a developed view of aportion of the barrel body, and Fig. (3 is an enlarged longitudinalsection of an end portion thereof with an end closure sgcured thereto. 7

Referring to the drawings-10 des gnates sheet-metal barrel body, whichhas transversely spaced portions n'cferably drawn inwardly at the endsthereof and compressed to provide the longitudinally e. lending endreinforcing ribs 11, and has similarly spaced inwardly drawn closely afull, clear, and exact description of the drawings, and to thefigcompressedpo'rtions at theiniddle thereof :rct as complete trusses ininforcing ribs 12.

The ribs 11 at opposite ends of the body are arranged to longitudinallyregister with each other, and the ribs 12 preferably alternate therewitharound the body, as shown. The end ribs 11 are of greatest depth attheir outer ends and gradually diminish toward the'centcr of thepackage, preferably dying out or losing themselves in-the pack age bodyslightly short or its center.

The middle reinforcing ribs 12 are of greatest depth at. the center ofthe package and gradually diminish outwardly preferably from pointswhich approximately register transversely with the inner ends of theribs 11 until they lose themselves in the body adjacent its ends. Theribs are of suitable depth and preferably diminish at their ends in suchproportion relative to the ribs 11 as to make the barrel body ofapproximately equal strength throughout its length. The end ribs 11, inaddition to re,- inforcing the body are also of suitable depth andsutiiciently tapered to give the body the proper bilge.

The ribs 11 and 12 at the'ends of the package body are rolled flatagainst the body to form the customary closure receiving portions orchimes at such ends. If it is desired to double-seam the outer edge of aclosure with the body edge, as shown at 13, the outer ends of the ribs12 may be cut away to provide a flange ll for interlocking with theclosure edge. The chime is shown in the present instance as beingreinforced by a band 15.

It. is evident that I have provided a bilged sheet metal package, which,instead of being of minimum strength at its central portion is, ifanything, of greatest strength at such portion. as the middle ribsslanting oil to both sides and being deepest in the middle resisting anypressure from without. l' urthermorc the end ribs. rmming only one wayserve toi'give thepackage the proper bilge shape, and also the necessarystrength at the package ends, instead of these ribs producing a completetruss construction they form two halves of a truss pulling in oppositedirections which, when taken alone, produce a package of weak contraconstruction, but when combined with central ribs-running in the samedirection cooperate tli'erewith to'- produce. a t

package of very great strength at its central portion, where strength ismost desired. It is also evident that my construction of bilged package.enables manufacturers to use very much lighter metal in its constructionthan is possible with any other metallic package of its nature on themarket, dueto the peculiar arrangement of ribs which impart greatresisting strength to the package.

I wish it understood that my invention is not limited to anyspecificconstruction 0r arrangement of the parts except in so far assuch limitations are specified in the claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is,

1. A bilged metallic package, having alternating sets of central and endribs,- all run ning longitudinally of the package with both ends of thecentral 'ribs extending between the inner ends of the contiguous endsets of ribs to' cooperate therewith to strengthen the packagethroughout its length.

2. A'bilged metallic package, having central and opposite end sets ofclosely compressed ribs, with both ends of the central ribs lapping thecontiguous ends of the end ribs.

3. A bilged metallic packa e having longitudinally-extending and bilgingribs in each end portion thereof and center reinforcing ribs.alternating with at least a portion of the end ribs and extendingoutwardly at their ends beyond the inner ends of the end ribs.

minishing in depth to their inner'ends, andv center reinforcing ribswhich have their ends extending outwardly beyond the inner ends of theend ribs and gradually diminishing in depth.

5. A bilged metallic barrel having its body-comprising a single pieceand provided at its ends with longiti1dinal1yextending bilging andreinforcing-ribs, whichter'minate at their inner ends adjacent thebarrel center, and provided at its central portion withlongitudinally-extending ribs, which are of greatest depth at the barrelcenter andhave their ends extending betweenv the associated end ribs andgradually diminishing in depth.

(L'A bilged sheetm'etal barrelbody hav ing end bilging and reinforcingribs and center reinforcing ribs extending longitudinally thereof, theend and centerribs alterdepth toward their inner ends and losingthemselves in the body adjacent its center and the center .ribsdiminishing in depth from their centersbutwardly and losing themselvesin thebody adjacent its ends.

In testimony whereof, I have hereunto 'nating, withthe end ribsdiminishing in j signed my name to this specification in the presence oftwo subscribingwitncsses BIRGER QSLAND.
